Noise-reducing or vibration-damping support system for a pump for a vehicle seat

Abstract

A vehicle seat includes a pump for operating a seat cushion adjuster or a seat massage system and a seat frame structure. The pump is coupled to an electrical supply line and a pressure line. The pump is designed without a soundproofing enclosure. At least one noise-reducing or vibration-damping coupling device is provided. The coupling device and pump being attached via a first section to the seat frame structure. The coupling device is attached directly to the pressure line of the pump or to the electrical supply line of the pump via a second section.

The invention claimed is: 
     
       1.

       2. The noise-reducing or vibration-damping support system for a pump ( 1 ) for a vehicle seat as set forth in  claim 1 , characterized in that said at least one noise-reducing or vibration-damping coupling device ( 4 . 1 ;  4 . 2 ) exhibits a flexible section ( 4 . 1   a ;  4 . 2   a ) and a vehicle seat frame structure connection section ( 4 . 1   c ;  4 . 2   c ) designed as an attachment section for the attachment of said at least a one noise-reducing or vibration-damping coupling device ( 4 . 1 ;  4 . 2 ) to the seat frame structure. 
     
     
       3. The noise-reducing or vibration-damping support system for a pump ( 1 ) for a vehicle seat as set forth in  claim 2 , characterized in that the flexible section ( 4 . 1   a ;  4 . 2   a ) exhibits a hose section. 
     
     
       4. The noise-reducing or vibration-damping support system for a pump ( 1 ) for a vehicle seat as set forth in  claim 3 , characterized in that at least a portion of the hose section ( 4 . 2   a ) is designed as a shrink hose. 
     
     
       5. The noise-reducing or vibration-damping support system for a pump ( 1 ) for a vehicle seat as set forth in  claim 1 , characterized in that said noise-reducing or vibration-damping support system for a pump ( 1 ) comprises said first noise-reducing or vibration-damping coupling device ( 4 . 1 ) and a second noise-reducing or vibration-damping coupling device ( 4 . 2 ), whereby the second noise-reducing or vibration-damping coupling device ( 4 . 2 ) is attached directly to the electrical supply line ( 2 ) of the pump ( 1 ). 
     
     
       6. The noise-reducing or vibration-damping support system for a pump ( 1 ) for a vehicle seat as set forth in  claim 5 , characterized in that the second coupling device ( 4 . 2 ) is connected to the electrical supply line ( 2 ) of the pump ( 1 ) by means of a shrink hose.
